Product--DIAOHGM/CYLINDER ACTUATED DIAOHGM VALVE


WY-D04DP	–Features: 　 Inside the body to contact with liquid can be lined with corrosion-resisting material such as porcelain, rubber Ideal for slurry fluid and suitable for coagulative, adhesive fluid too. 　Inside structure of the body is so simple without sliding part nor moving part, and so smooth that phenomena of precipilation and accumulation of solid particles are difficult to occur. In addition, passage wall is also excellent in its errosion-resistance, and the durability is further reforced by lining with porcelain or rubber and all the corners inside the body can be cleaned up. 　Gland packing is not necessory, as it is sealed by diaphragm, thus there is no leakage. Cv value is about 1.5 times higher, compared to the conventional globe valve. Porportional control can also be applied.
